Association

In genetic epidemiology, an association is the observed connection between a trait and a particular version of a gene or other genetic variant.

Genome-wide association studies (GWAS) are used to pinpoint variants associated with complex disorders or traits, which are caused by the interaction of multiple genetic and non-genetic factors.
